cakephp accessing view attributes/variables from within a helper

Cake 2.x and 3.x

You can look up your variables in the _View object:

$this->_View->viewVars['foo'];

Cake 1.x

If you grab the current view object from within the helper you should be able to get to its passedArgs.

class SomeHelper extends AppHelper {
  function __construct($settings = array()){
    $this->passedArgs = ClassRegistry::getObject('view')->passedArgs;
  }
}

Cake 1.2.x

If you grab the current view object from within the helper you should be able to get to its viewVars.

class SomeHelper extends AppHelper {
  function __construct($settings = array()){
    $this->viewVars = ClassRegistry::getObject('view')->viewVars;
  }
}

Enjoy, Nick

Have you tried just setting the view's value from the AppController?

class AppController extends Controller {
 function beforeFilter() {
  // other stuff
  $this->set( 'passed_args', $this->params['pass'] );
 }
}
